I know that this topic has been discussed several times but I would need your opinion focused on my context.
I currently have NDS/SC(nonDR)/252/300(nonDR)/SBLMKII
I have the opportunity to trade in my 300 for a much newer 300DR, which will initially work with SBLs but I’m already scheduled to purchase some fantastic SL2s in September.
From what I see in the various topics it would seem that the 300DR should be brighter and brighter than the 300. In my case I fear that this might not be an improvement as the SBL (and then the SL2) are already quite bright.
The questions I would like to ask you are:
by taking the 300DR do I risk making the sound too bright and shrill with my SBL/SL2?
at the moment I have no possibility of converting the SC into DR. Could this be a problem if the 300 becomes DR?
I don’t intend to change the current speakers except for the SL2s.
I have always had DR SC with my 252, and I went from 250DR to 300DR, so I cannot make the comparisons that might be helpful. However, I can say that with SL2s and 252/SCDR/300DR the sound is certainly not bright or shrill - rather detailed, clear, well articulated bass, musical and not fatiguing. You don’t mention sources and this is with CD555/555PS DR and a well set up LP12.
Perhaps these are the question you have to ask yourself.
Is all servicing fairly up to date?
What weakness. or issue am I trying to address?
Proceed with caution unless you can audition first
Any powerlines or Naim Fraim in your system?
Search on the forum for those who have posted re similar upgrades - doubtless there will be lots, so consider wisely
Philosophy has often been source first - at a minimum service 252 (if nec) then upgrade SC to SCDR - if you like 252, then give it the likely better PS
NDS might benefit from DR PS - choice of two
If you start on DR route - strongly consider that you may need to complete the journey; ymmv
If budget is limited, consider wisely, perhaps rather than single items!
It all comes back to audition - for your ears, rather than what we might propose
I would be very surprised if the 300DR is too bright but of course much depends on the room. I run a 300DR with Kudos 606. I would say that the 300 DR has more body than the 250DR I would not describe the overall balance as bright. That probably doesn’t help enormously but it may provide some context.
I’m surprised that you find the SBLs bright. I had them before the SL2s and have found neither bright, although this could be room dependent - they were both in the same room.
I have a 300 into SL2 which I got the DPR upgrade for and certainly I did not notice any added brightness. I don’t know where you’re getting this information from.
If your 300 is due with service and you can get a DR for perhaps under the cost of a service go for it.
Certainly the bright sound that I perceive also depends on the room (as it should be because each environment has its own characteristics).
Unfortunately, there is very little I can do about this aspect because the system is in the living room where we all live and my wife doesn’t allow me to do any acoustic treatment. So I have to live with it.
My plan is definitely to switch everything to DR if I get the chance.
I ran my SL2’s with a 300, which I then had upgraded to DR spec. I found both fantastic, although the 300DR was slightly preferable (stronger bass, a little more lively sound).
I’ve got an untreated room with lots of reflective surfaces (polished wooden floors, lots of glass), and I’ve not found brightness to be an issue at all.
My configuration was used with both a 252 and then a 552.
I have mulled this over on occasion as I have an original 300 that is now 20 years old. I have heard the DR many times at my dealers but not at home. It always came over a bit bright and analytical to me. Enough to keep (and service) my 300 and not ‘upgrade’. I would look at a 555 as others have said. That’s what I did!
Have to disagree, my experience of a 300DR was that it wasn’t brighter than the 300 that preceded it. It was however a much better amp. I was very pleased with the upgrade and wouldn’t hesitate if I were in the same position as you.
Of course! I remember when I got my 300, I thought things had become “serious”; the 250s before it were always good but the 300 was a really big step up.
It’s just that …. well, the DR upgrade took it a lot further. I could have stayed there quite happily had I not finally home demoed a 500DR.
